Stereoscopic video display apparatus and display method

Abstract

A stereoscopic video display apparatus according to an embodiment includes: a display panel having a display face on which pixels are arranged in a matrix form; an active lens disposed in front of the display panel to control light rays from the pixels, the active lens being capable of conducting partial changeover on a focus state of the display face; a defocus region detection unit configured to detect a region to be subject to focus processing from an image which is input; and a drive unit configured to drive the active lens to conduct defocus processing on a region to be defocused, which is detected by the defocus region detection unit.

What is claimed is: 
     
         1 . A stereoscopic video display apparatus comprising:
 a display panel having a display face on which pixels are arranged in a matrix form;   an active lens disposed in front of the display panel to control light rays from the pixels, the active lens being capable of conducting partial changeover on a focus state of the display face;   a defocus region detection unit configured to detect a region to be subject to focus processing from an image which is input; and   a drive unit configured to drive the active lens to conduct defocus processing on a region to be defocused, which is detected by the defocus region detection unit.   
     
     
         2 . The stereoscopic video display apparatus according to  claim 1 , wherein the region to be defocused is a region where a gray scale level or color is monotonous, or a region where a projection or depth quantity is larger as compared other regions. 
     
     
         3 . The stereoscopic video display apparatus according to  claim 1 , wherein the defocus processing is conducted by shifting a focal length of the active lens. 
     
     
         4 . The stereoscopic video display apparatus according to  claim 1 , wherein
 the active lens is a GRIN lens, and   the defocus processing is conducted by applying voltages of different combinations to the GRIN lens.   
     
     
         5 . The stereoscopic video display apparatus according to  claim 1 , wherein
 the active lens comprises a double refraction lens provided in front of the display panel and a polarization switching cell for lens control provided between the double refraction lens and the display panel, and   the defocus processing is conducted by applying voltages of different combinations to the polarization switching cell for lens control.   
     
     
         6 . The stereoscopic video display apparatus according to  claim 1 , further comprising a position detection unit to detect a position of a viewer,
 wherein the defocus processing is conducted by using the position of the viewer detected by the position detection unit.   
     
     
         7 . A stereoscopic video display method for displaying a video on a stereoscopic video display apparatus including a display panel having a display face on which pixels are arranged in a matrix form, and an active lens disposed in front of the display panel to control light rays from the pixels, the active lens being capable of conducting partial changeover on a focus state of the display face, the stereoscopic video display method comprising:
 detecting a region to be subject to focus processing from an image which is input; and   driving the active lens to conduct defocus processing on the detected region to be defocused.
